I think he means to move the pagefile to the mechanical drive, as this will consume read/writes and SSDs are only so durable. Although I have heard from other users their pagefile doesn't eat too many cycles up, but this will vary on system usage and amount of RAM (and you have 12GB so you may even be able to turn it off!)
Vertex 3 is the next best option after pci-e based storage! I believe it should be very easy to install, Windows 7 should allign the partition correctly and you will be running in no time! Vertex 3 is the fastest Sata SSD on the market currently (for the consumer at least), the majority of applications will open almost instantly and boot times will probably be cut by at least half!
EDIT: That motherboard doesn't have SATA 3 ports right? (rev 1.0) That means it will bottleneck the Vertex 3 by quite a bit, but should still be night and day versus your old drive!
